Application August 31, 1954, Serial No. 453,397

3 Claims. (Cl. 132-7) The present invention relates to the method and apparatus for facilitating the neutralizing of permanent wave solution applied to a head of hair.

Heretofore in neutralizing permanent wave solutions, the neutralizer solution has been applied by saturating an absorbent body and patting it on the hair while on the rods after the permanent wave solution has been applied thereto. Another method has been to cup it on the hair.

Both of these methods are time-consuming and are messy particularly when it is necessary to re-position the head of the person to enable the neutralizer to be applied to the hair at the nape of the neck. Further they are uncertain because of the difficulty in obtaining proper distribution and penetration of the neutralizer. Because of this uncertainty there has always been a question as to the tightness of curl which will be obtained and for this reason it was believed necessary to wind the hair on a small rod so as to permit some spring back and still retain the proper curl. The use of the small rod, however, re quired a large number of turns thereon and this increased the thickness of the hair and the difiiculty of penetration thereof by the neutralizer solution.

The present invention overcomes these difficulties by providing a method and means whereby the neutralizer may be sprayed on the exposed hair with sufficient force to cause penetration thereof and to permit application of the neutralizer in required amounts thereby obtaining uniform control of the curl.

This is accomplished by providing a container into which is placed the required neutralizer solution for neutralizing a single permanent wave and pumping from the container to a manually directed sprayer the neutralizing solution which is applied by the operator to the hair on the head of the person receiving the permanent wave, which head is positioned over a collecting means or tray communicating with the container to collect the excess sprayed neutralizer and direct it back to the container to be re-used during the neutralizing operation.

A feature of the invention resides in the fact that by spraying the neutralizer under pressure better penetration of the curled hair is obtained and also the operator can more readily apply and direct the spray to the curls as required.

Another feature of the invention resides in the fact that because of the better penetration of the curls by the neutralizer, I am able to wind the curls on a larger rod and still provide the satisfactory curls.

Other features and advantages of the invention will be apparent from the specification and claims when considered in connection with the drawings in which:

Figure I is a perspective view showing the apparatus in position for carrying out the method.

Fig. 2 is a detailed view, partly in section, of the pump.

In accordance with the present invention a container 10 is provided which is adapted to be mounted on a suitable table or other supporting means 11. The container 10 is adapted to have placed therein a neutralizer solution 12 for neutralizing the permanent wave solution that has been applied to the hair on the head of the person receiving the permanent wave. This is usually supplied in sufficient quantity to neutralize a single permanent wave. In order to apply the neutralizer solution, the container 10 is provided with a pump 13 adapted to pump the neutralizer from the container to a manually directed sprayer 14. While the pump may be an integral part of the container, in the preferred form of the invention the pump 13 is a separate sump type pump adapted to be positioned in the container and comprises a housing 15 and an electric motor 16 connected by suitable wires 17 to a source of power. The motor drives a pump unit 18 to pick up the neutralizer solution and force it through the hose 19 to the sprayer 14. As shown in Fig. 1, the person having the permanent Wave is seated in a chair 20 adjacent the table 11 and a collector means or tray 21 is provided, preferably adjustably carried by the back of the chair, and positioned so that it is in communication with the container. The persons head is placed at the upper end of the tray with the hair to be neutralized located over the tray as shown in Fig. 1. It will be noted that the hair which is wound on rods 22 is in an exposed position so that the operator has full view of the hair and can manually direct the spray to all of the curls, particularly those at the nape of the neck, without changing the position of the person.

The neutralizer being pumped from the container with a certain amount of pressure will cause the spray to have a penetrating effect and penetrate the hair wound on the rods 22. The excess neutralizer solution will run from the hair into the collector or tray and return to the container to be re-used. This manner of using the given amount of neutralizer solution will permit the neutralizing operation to continue for the required length of time.

Since the hair is in exposed position the operator is provided a full view during the neutralizing operation and can manually direct and spray the neutralizer solution as required to insure a uniform and complete neutralization of the wave. Because of the controlled distribution and better penetration of the sprayed neutralizer solution, I have been able to control more accurately the neutralization of the permanent wave.

Inasmuch as the neutralization of the waving solution is more complete with my method, I have been able to wind the hair on rods of larger diameter, thus reducing the thickness of the hair on the rod, which further removes the difiiculties of penetration encountered with a smaller rod and yet retains a proper curl.

Thus, it will be seen that I have provided a novel method and apparatus whereby the neutralizer is sprayed by a manually directed sprayer to elfectively neutralize the permanent wave solution in a simple, yet economical manner to provide a uniform curl in the hair.

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.

I claim:

1. The method of neutralizing the permanent waving solution applied to a head of hair of a person comprising the steps of positioning a collecting means only about the neck of the person thereby leaving the head of the person having a permanent wave solution on the hair in an unobstructed exposed position over the collecting means, spraying the neutralizer solution under pressure, and manually directing the spray over the exposed unobstructed hair on the head of the person having a permanent wave solution thereon to cause it to be properly distributed thereover and penetrate the wound hair to completely neutralize the permanent wave solution thereon.

2. The method of neutralizing the permanent waving solution applied to a head of hair of a person comprising the steps of positioning a collecting means only about the neck of the person thereby leaving the head of the person having a permanent wave solution on the hair in an unobstructed exposed position over the collecting means, pumping neutralizer solution from a container having therein a predetermined quantity of neutralizer solution sufiicient to neutralize a single permanent wave, manually directing the spray and spraying the neutralizer solution over the hair having permanent waving solution thereon to uniformly neutralize the same, and returning the excess neutralizer solution being collected by the collecting means to the container to be reused during the neutralizing operation.

3. The method of neutralizing permanent waving solution applied to a head of hair of a person comprising the steps of placing a predetermined quantity of neutralizer solution sufficient to neutralize a single permanent wave in a container having a pump and a connected manually directed sprayer, positioning a collecting and return tray only about the neck of the person having a permanent wave solution on the hair thereby leaving the head unobstructed and in an exposed position over the collecting and return tray, connecting the return tray with the container, pumping the neutralizer from the container and manually directing the spray and spraying the neutralizer solution over the exposed hair to uniformly neutralize the permanent wave solution thereon with the excess neutralizer solution being collected by the tray and returned to the container to be reused during the neutralizing operation.
